return-to-zero
Electronics
adjective
Designating a binary signal which returns to 0 following each bit, regardless of whether the following bit is 0 or 1; relating to or involving such signals; opposed to non-return-to-zero.
- A return-to-zero signal acts as its own clocking signal. As half the signal time is spent at zero, a return-to-zero signal can only store half as much data as a non-return-to-zero signal..
